Shooting from the highway bridge in Tehran Highway: hack or bug?

In Battlefield 3's Tehran Highway map, I often notice (for the most part) opponents shooting from the highway bridge itself, almost undisturbed.

Honestly I'm on BF3 since a certain time actually, but I can't figure out how to climb up there.

Is it a hack or is it a bug?


Solution 1:

It's an exploit.

It is possible to reach the overpass by riding the MAV (a remote-controled, flying gadget for the recon kit intended to be used for reconnnaisance). Currently, a player can deploy the MAV, stand on top of it, fly it straight upward to an area above the overpass, then jump off.

The ability to ride the MAV is being removed in the upcoming patch. Patch notes can be found here.

-The MAV can no longer be used as an elevator.
